I did not use the Makefile for this. I created a project file,
included all the header files and source files in the sqlplusint
folder, and created a static library using MinGWStudio.

I'm not used to using makefiles as I moved from a window's environment
and am used to IDEs generating project files. Yes, I have started
reading up the documentation on GNU make. It appears that I need to
modify the makefiles that you've provided ( I'm not sure
at this point what I need to do - hopefully the documentation on GNU
Make will clear some things up.

Yes, I believe it is a problem with linking against he wrong library.
I may have to get hold of the MySQL source and create the library
myself. I was wondering whether anyone else had run into this problem
and solved it themselves.

Yes, I tried that. Created a very simple program that had problems
with linking against the MySQL C libraries. I was able to make the
link work by using the libmysql.dll, creating a libmysql.def using
dlltool etc. following instructions I found on the windows subsection
of the following web-site. I could create the executable but it didn't

Thanks for the really prompt reply.
